/etc/default/glb-director - Configuration around the DPDK EAL runtime and other similar configuration options, used by systemd.

/etc/glb/director.conf - The default location for the configuration of how the director processes packets on CPU cores and on ports/NICs.

/etc/glb/forwarding_table.json - The default location for the forwarding table when healthchecking is not used.

The glb-director runs with systemd under the glb-director.service unit.

Director tier: glb-healthcheck

The glb-healthcheck application runs tunnel and HTTP healthchecks on a source GLB forwarding table, writing out a new table that glb-director can consume that takes into account health state of backend proxy servers.

Installation on Debian:

sudo apt install glb-healthcheck

To configure the healthchecker to work with glb-director, the /etc/default/glb-director will need to be updated to reflect the /etc/glb/forwarding_table.checked.bin version.
